Abstract:

The electro–reduction of CeO2in eutectic CaCl2–NaCl melt was studied by cyclic voltammetry and constant voltage electrolysis techniques. One cathodic current peak in the cyclic voltammogram was observed and supports a one–step electro–reduction mechanism of CeO2. During different times of electrolysis at 800°Cof temperature and 3.0V of constant voltage, the products CeOCl and CeO2were observed by XRD and confirms the following electro–reduction sequence: CeO2CeOCl.

Abstract:

The treatment of metal-contaminated sediment generated in environmental dredging projects often requires both reduction and remediation, and the electric field has good application prospects in the integration of reduction and remediation. In this study, based on the electro-osmosis, vacuum, and vacuum electro-osmosis methods, a detachable test system was made. Experiments of the three methods were carried out independently on the reduction and remediation of dredged sediment from Tai Lake under pollution-free and Cu-contaminated conditions. The results show that copper contamination weakens the effect of reduction, and the production of copper precipitates makes the soil more prone to cracking and blocking drainage channels, which has the greatest impact on the electro-osmosis method. In terms of copper concentration, vacuum electro-osmosis achieves the transport and discharge of contaminants, and has the best remediation effect. The removal rates at the anode and cathode are 45.1% and 50.0%, respectively. A correlation model based on electrical conductivity, moisture content, and contaminant concentration was established to facilitate the determination of contaminant concentrations in actual projects. Electro-migration plays a dominant role in the remediation process, and the reduction affects the electric field distribution and, thus, the migration efficiency.

Abstract:

Objectives : The effect of current density and contact time of electro-coagulation on membrane fouling was investigated. In order to elucidate the reason why the membrane fouling was reduced by electro-coagulation, the changes in the characteristics of activated sludge were examined before and after electro-coagulation.Methods : A series of electro-coagulation of activated sludge suspensions was carried out with current density of 2.5, 6, 12, 24 A/m2 for 0, 2, 6, 12 hours. After membrane filtrations of the activated sludge suspensions, the membrane fouling was compared before and after the electro-coagulation. Characteristic changes in the activated sludge were also analyzed quantitatively.Results and Discussion : Total fouling resistances (Rt) of the electro-coagulated activated sludge decreased as current density and contact time increased. For example, Rt decreased 15%, 63% and 86% under the condition of current density of 24 A/m2 and 2, 6, 12 hours of contact time. Particularly, three activated sludge suspensions having very different initial MLSS concentrations showed a similar reduction of Rt, indicating that the membrane fouling was reduced not dominantly by particulates but by soluble foulants. The MLSS increased as current density increased, but MLVSS had not changed accordingly, which means that inorganic solids such as Al(OH)3 and AlPO4 produced during electro-coagulation were the main reasons for the increased MLSS concentration. These solids could play a key role in the reduction of membrane fouling by means of a dynamic membrane. As current density increased, the EPS (extracellular polymeric substances) and soluble COD concentration were reduced, which led to the reduction of membrane fouling. Soluble TN and TP were not significantly changed after electro-coagulation.Conclusions : The fouling materials, particularly, EPS and soluble COD decreased as current density and contact time increased, which played a key role in the reduction of membrane fouling. In addition, the insoluble solids produced during the electro-coagulation would act as a dynamic membrane, which led to fouling reduction.

L'addition de l'acrylate de methyle sur un dialdehyde, en presence de diazabicyclooctane, suivie d'une reaction d'acetylation est une voie d'acces simple a des precurseurs de cyclophanes et de cryptands. L'utilisation de divers dialdehydes comme l'isophtalaldehyde, des isophtalaldehydes substitues, le furanne 2,5-dicarboxaldehyde et un dialdehyde qui derive de la disubstitution d'un dihalogenure d'alkyle par un hydroxybenzaldehyde a permis de generaliser cette methode de synthese. Des cryptands symetriques, des orthocyclophanes et un metacyclophane sont ainsi obtenus par action de l'ammoniaque. L'addition de diacetates, autre que le para di(acetoxy-1 methoxycarbonyl-2-propene-2 yl) benzene, sur le diaza 7,7 paracyclophane tetraene donne des cryptands dissymetriques et un macrobicycle asymetrique.

Les modifications de conformation sous l'effet de la protonation, de la complexation d'acides ou des substitutions, ont ete examinees. Le diaza 7,7 paracyclophane tetraene et le cryptand correspondant ont fait l'objet d'une etude electrochimique. La reaction est etudiee par voltammetrie cyclique

Abstract:

In this work, molecular complexes of transition metals have been synthesised and studied for their CO2 reduction ability, either in an electrochemical or photochemical system, with a focus on complexes of nickel with derivatives of the macrocycle cyclam (cyc, cyc = 1,4,8,11-tetraazacyclotetradecane) which are well-known for being extremely active CO2 reduction electrocatalysts in water. The cyc framework has been modified with functional groups suitable for binding to semiconductor oxides to obtain the new complexes Ni(cycC) and Ni(cycP) (cycC = 1,4,8,11-tetraazacyclotetradecane-6-carboxylic acid, cycP = {[(1,4,8,11-tetraazacyclotetradecan-1-yl)methyl]phosphonic acid}), and their electrochemical activity towards CO2 reduction in water has been evaluated. Modification of the ligand framework in the 6 position with a carboxylic acid does not change the CO2 reduction activity of the complex Ni(cycC) at pH 5, through the use of electrochemical and spectroscopic techniques it was found that there is a large increase in the CO2 reduction activity at pH 2, proposed to be due to the protonated carboxylic acid acting as an internal proton source. When Ni(cycC) was immobilised on TiO2 electrodes it was possible to measure the rate of photoinduced electron transfer by using μs-s transient absorption spectroscopy (TAS) under argon in the presence of a hole scavenger, however the carboxylic acid proved unstable under CO2. Ni(cycP) was synthesised to provide a stronger binding group to the surface. It was found that functionalisation on the 1 position affected the CO2 reduction activity in a negative way, however the complex was able to bind strongly to both TiO2 and ZrO2. ZrO2 nanoparticles modified with Ni(cycP) and a ruthenium dye were able to reduce CO2 to CO in water at pH = 4, with higher rates and turnover numbers compared to the components in solution, when illuminated with visible light. The improvement in activity for the heterogeneous photocatalyst was attributed to a faster electron transfer from the immobilised dye to the immobilised catalyst, calculated through detailed steady-state and transient spectroscopies, which prevented charge recombination. In collaboration with the University of Cambridge, Ni(cycP) has been immobilised on ZnSe quantum dots (QDs) and it has been proven to be an effective photocatalyst for CO2 reduction to CO in water. We have carried out a detailed ultrafast TAS study on suspensions of the modified QDs, and it has been found that in the presence of a hole scavenger, upon illumination the electrons are excited from the VB to the conduction band (CB), however they rapidly decay to trap states close to the CB to generate a long lived signal. When Ni(cycP) is present, faster decay of the trapped electron signal is observed, which is assigned to fast electronic transfer from the QDs to Ni(cycP). The knowledge of the mechanisms for CO2 reduction will allow rational design of better catalysts for CO2 reduction. In collaboration with the Rutherford Appleton Laboratories, we have designed an in situ spectroelectrochemical Sum Frequency Generation (SEC-SFG) technique using the ULTRA laser at the Central Laser facility. We have demonstrated the technique by analysing the redox behaviour of a well-known CO2 reduction catalyst, [Mn(bpy)(CO)3Br]. We were able to observe the redox species at the electrode surface as a Cyclic Voltammogram was carried out, and to propose the orientation of the species at the surface. Furthermore, the same technique has been applied to the study of the absorption mechanism of Ni(cycC) on the mercury surface, the first step in the catalytic cycle.

Abstract:

<p> The dioxygen reduction reaction (ORR) is a key process for renewable energy technologies such as batteries and fuel cells. Reliance on dioxygen as the terminal oxidant in fuel cell technologies requires the development of electrocatalysts that proceed at low overpotentials with fast rates, while maintaining adequate selectivity for H<sub>2</sub>O production over thousands of hours of operation. While many advances have been made, the discovery of efficient and inexpensive ORR electrocatalytic materials remains a holy-grail of energy science. The study of soluble, molecular electrocatalysts allow for more detailed structure : activity analyses to be made than for electrocatalytic materials, providing an atomic level understanding of catalytic barriers and opportunities for improvement.</p><p> Chapters 1-5 of this thesis develop a rational approach for analyzing, comparing, and improving homogeneous and molecular ORR electrocatalysts in non-aqueous solvents, and use this approach to study the reduction of dioxygen to water using iron porphyrin electrocatalysts. Quantification of the equilibrium potential for O<sub>2</sub>/H<sub>2</sub>O under the conditions of study allowed, for the first time, accurate estimations of the reaction overpotential in non-aqueous solvents. Knowledge of the reaction overpotential proved critical for comparing electrocatalysts under the somewhat diverse conditions encountered for homogeneous catalysts with varying solubilities in organic solvents.</p><p> A detailed kinetic and mechanistic study was then conducted on iron tetraphenyl porphyrin, Fe(TPP), which revealed that the turnover limiting step is protonation of the iron(III) superoxo adduct, formed via pre-equilibrium dioxygen binding to Fe<sup>II</sup>(TPP). The protonation step was found to have a large kinetic barrier, suggesting that targeting proton delivery to the active site may improve the ORR activity of iron porphyrin electrocatalysts.</p><p> Studies of eleven substituted iron porphyrin ORR electrocatalysts all showed high selectivity for the 4H<sup>+</sup>/4<i>e</i><sup> -</sup> reduction to water. The turnover frequencies (TOFs) were found to correlate with the reduction potential required to initiate electrocatalysis, in two log(TOF):overpotential linear free energy relationships (LFERs). The iron porphyrin electrocatalysts with well-positioned proton donors above the active site fell upon the same LFER as those without such proton relays, suggesting that the second coordination sphere does not directly participate in the rate-limiting proton transfer. These results contradict the general sense that well-positioned proton relays should decrease kinetic barriers. However, some iron porphyrin catalysts in the series can break the LFER, leading to more efficient catalysis. Computational studies suggest that, rather than directly participating in an intramolecular proton transfer, the second coordination sphere of some iron porphyrins can hydrogen bond with the O<sub>2</sub> adduct to influence the thermochemistry for proton transfer. Importantly, the presence of these LFERs was shown to stem from the electrocatalyst <i>E</i><sub>1/2 </sub> influencing the thermodynamics for O<sub>2</sub> binding and proton transfer. Analogies are drawn between these linear free energy relationships and the scaling relationship analyses used for electrocatalytic materials for the ORR.</p><p> Using the mechanism, rate law, and thermochemistry, the log(TOF) : overpotential correlations were then derived for ORR catalyzed by iron porphyrins. Given that the TOF is a function of the catalytic rate law (TOF = <i>k</i><sub> cat</sub>[O<sub>2</sub>][HA]) and the overpotential is a function of the reaction conditions, the predicted correlation between log(TOF) and effective overpotential is independently. derived for changes in the reaction conditions or for changes to the catalyst <i>E</i><sub>1/2</sub>. For each parameter varied, a unique correlation coefficient was identified and shown to agree with experimental data. The very shallow dependence between log(TOF) and the p<i>K</i><sub> a</sub> of the acid used was used to enable Fe(TPP) catalyzed ORR to break the prior LFERs by 10<sup>4</sup> s<sup>-1</sup> in TOF. These scaling relations highlight how decoupling the ET, PT and substrate binding events can lead to diverse scaling relationships, providing opportunities for improving the activity of a <i>catalytic system</i> by targeting the medium, as opposed to the catalyst.</p><p> In chapter 6, an exploratory research project on driving the ORR using sunlight to produce hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) is discussed. H<sub>2</sub>O<sub>2</sub> is a commodity chemical with diverse applications in water purification, as an oxidant, and as a liquid fuel. Preparation of nickel(II) oxide photocathodes sensitized with simple dyes revealed that these photocathodes are surprisingly active for H<sub>2</sub>O<sub>2</sub> production, proceeding to produce H<sub>2</sub>O<sub>2</sub> with unity faradaic efficiency at low overpotentials (<20 mV). The reaction is found to proceed via outer sphere electron transfer from reduced dyes to O<sub>2</sub>, forming superoxide, which disproportionates in solution, forming H<sub>2</sub>O<sub>2</sub>. Remarkably, these unoptimized systems are among the most active photocathodes for H<sub> 2</sub>O<sub>2</sub> production. These results are promising for developing the delocalized production of H<sub>2</sub>O<sub>2</sub> using dye-sensitized photoelectrosynthesis cells.</p><p>

Abstract:

Le couplage d’un traitement électrochimique avec un procédé biologique est une alternative prometteuse pour la dégradation de composés organo-halogénés biorécalcitrants dans l’environnement. Les procédés d’électroréduction, connus pour couper sélectivement la liaison carbone-halogène, ont été mis en oeuvre afin de réduire la toxicité des molécules cibles et augmenter leur biodégradabilité avant une minéralisation totale des polluants par un traitement biologique. Pour améliorer le rendement de déchloration, la cathode préalablement nickelée a été modifiée par des nanoparticules d’argent car l’argent est considéré comme l’un des meilleurs catalyseurs pour couper sélectivement la liaison carbonehalogène. Le feutre de graphite a été choisi comme support d’électrode pour sa grande surface spécifique. Le principal produit de déchloration de l’alachlor s’est révélé être biorécalcitrant. Pour surmonter ce problème, un traitement par procédé électro-Fenton a été mis en oeuvre pour dégrader les polluants cibles. Une amélioration significative de la biodégradabilité de la solution d’alachlor a pu être observée après le traitement électro- Fenton, et qui est renforcée quand l’atome de chlore a été préalablement éliminé de la structure de l’alachlor par électroréduction. Le bismuth a été également utilisé comme support d’électrode du fait de sa grande surtension visà- vis de la réduction de l’eau. Une grande sélectivité a pu être obtenue sur cathode de bismuth lors de la réduction d’herbicides du type chloracétamide. La réduction électrochimique du dioxyde de carbone a également été réalisée sur électrode de bismuth modifiée par des nanoparticules d’argent comme autre application de cette nouvelle électrode<br>Electrochemical process coupling with a biological treatment is a promising alternative for the degradation of biorecalcitrant organo-halogenated compounds in the environment. The electroreduction treatment, known to cut selectively carbon-halogen bonds, was first implemented to decrease the toxicity of the target molecules and increase their biodegradability before a complete mineralization of the pollutants by a biological treatment. To improve the dechlorination efficiency, the cathode was modified by silver nanoparticles after a previous nickelisation, since silver is considered as one of the best electrocatalysts to selectively cleave the carbonhalogen bond. The graphite felt was chosen as the electrode support due to its high specific surface area. For alachlor herbicide, deschloroalachlor, the main by-product after dechlorination, was still biorecalcitrant. To overcome this issue, electro-Fenton treatment, in which hydroxyl radicals were generated to degrade the target pollutants, was implemented. Significant improvement of biodegradability of the alachlor solution was observed after electro-Fenton treatment, which was further improved when the chlorine atom was beforehand removed from the alachlor structure by the electroreduction process. Bismuth was also used as electrode support due to its high overpotential for hydrogen evolution. A high selectivity of chloroacetamide herbicides reduction was observed on the bismuth based cathode. As an extended application of the bismuth based cathode, the electrochemical reduction of carbon dioxide was performed on Bi electrode modified by silver nanoparticles

Abstract:

Abstract E-fuels, produced from CO2 using renewable electricity, currently suffer from low energy efficiency, hence high energy demand, related high cost and are therefore not yet produced at industrial scale. To be commercially viable, e-fuels production pathways require the availability of vast amounts of low-cost electricity. The Horizon 2020 project EcoFuel, with the aim of overcoming these deficiencies, develops and demonstrates a novel process chain that significantly improves the energy efficiency for production of synthetic fuel out of CO2 and water using renewable energy. The process chain comprises a) the supply of CO2 from the atmosphere via a novel direct air capture (DAC) approach, b) direct electro-catalytic reduction of CO2 to C2/C3 hydrocarbons at close to ambient temperatures, and c) thermo-catalytic liquefaction of alkenes, upgrading and fractionation into transport fuels. The direct electro-catalytic CO2 reduction to hydrocarbons offers greatly enhanced efficiency potentials compared to Power-to-X technologies downstream of water electrolysis and at the same time, reduces process pathway steps. Overarching objectives of EcoFuel are to reduce primary energy demand, to enhance resource and cost efficiency of production, minimize the environmental footprint of the process, and to demonstrate the ecological and economic advantage.

Full text

Abstract:

Abstract Online Risk Monitoring and risk reduction of Corrosion Under Insulation (CUI) is described for use in critical industrial assets using Electro-Magnetic Guided Radar (EMGR) technique and with API 581 guidelines. Risk Based Inspection (RBI) is used to optimize the inspection plan but risk can be reduced with more field data about asset condition. Often inspection plan can be inefficient for CUI in critical assets where either over-inspection or under-inspection scenarios exist. A remote Risk Monitoring system using Electro-Magnetic Guided Radar (EMGR) is described in this paper. This technology involves use of sensors embedded in the insulation and a data logger transmits data wirelessly to a central server. Risk analysis and localization for CUI risk severity are then accessed by the end user to help optimize CUI inspection plan. This provides important data for asset managers to plan, schedule and target their efforts. This presentation will describe in more detail the principles of the technique and recent case studies from various deployments in the context of energy transition to low carbon fuels.

Full text

Abstract:

Abstract Many private-sector, federal government, and Department of Defense (DoD) facilities experience the problem of concrete deteriorating via alkali-silica reaction (ASR). ASR is a form of concrete corrosion that slowly deteriorates concrete from the inside by forming highly expansive gels that cause cracking and swelling of the concrete matrix. This paper summarizes the results of a project that evaluated Electro-Osmotic Pulse (EOP) technology to mitigate ASR in an area of the visitor’s ramp at Campbell Army Airfield. An EOP system was designed, installed, and monitored in a concrete pavement section affected by ASR. In addition to installing EOP technology, concrete moisture monitoring probes were installed at selected locations. The performance of the EOP system was evaluated by recording temperature and moisture levels inside the concrete for a period of nine months. The ability of the EOP system to mitigate ASR is inconclusive. Although there are indications that moisture is being removed from the concrete pavement, it is not clear that the concrete’s internal relative humidity has been reduced below 80%, the moisture reduction value that ensures ASR will not occur. A long-term approach for performance monitoring must be completed before the technology can be recommended.

Abstract:

Abstract Electrical Signature Analysis (ESA) was developed originally at Oak Ridge National Laboratory to allow diagnostic related information to be gathered from electric motor driven devices via a remote non-intrusive current measurement on a motor power cable. The resulting signal with appropriate processing is sensitive to mechanical and electrical perturbations occurring in the motor and driven system. This technique has been applied to many different types of AC and DC motors with various driven machines. Recently the ESA technique has been extrapolated to evaluate electro-magnetic devices such as alternators and generators via analysis of their voltage output signals. The primary goal of this study is to investigate diagnostic methods from established non-intrusive ESA methods and apply them to sound reduction in automobile alternators, diagnostics for rotor and gearbox for helicopter and aircraft generators, and diagnosis of gear problems and electrical winding health for airliner auxiliary power unit generators.

Abstract:

Trinidad and Tobago has a great opportunity to accelerate the deployment of electro mobility in the country. The electrification of the transport sector has the potential to reduce the countrys emissions and thus help the fight against the impacts of climate change, and improve peoples quality of life with the reduction of air pollution in urban centers. Moreover, the electrification of the transport sector increases energy security and presents a great opportunity to improve public transportation services to the population. This report, elaborated by the University of West Indies (St. Augustine campus) and the Inter-American Development Bank (IDB), aims to provide insights about a series of public consultations with stakeholders in the country, and has the goal of presenting the results as a contribution to the efforts the Government of the Republic of Trinidad and Tobago is already doing in the development of electro mobility. Investments in green and resilient infrastructure can contribute to the sustainable development of the country and thus improve the quality of life of the local society.
